ABSTRACT:
This disclosure relates to a joining structure for use in connecting pipes or tubes such as those which form a bicycle frame. The structure comprises a joining cylinder and a cylindrical part secured to the joining cylinder, the joining cylinder having an opening therein adapted to receive a pipe. A wall having a through hole is formed inside the opening of the joining cylinder, and an internal thread is formed in the internal periphery of the pipe. A core having on its external periphery an external thread which corresponds to the thread of the pipe is threaded into the pipe. The core has a threaded hole aligned with the through hole, and a bolt is provided for joining the wall and the core in such a manner that said bolt engages the wall and the core for joining the cylinder with the pipe.
